Sp'ecification of Letters Patent. P t t June 14, 1910,

Application filed August 21, 1909. serial No. 514,005.

To all whom it may concern: I

Be it lmownthat I, JOHN HENRY U'I'LEY, a subject of the of Great Britain, residing in the city of Camden, State of New Jersey, have invented certain new and useful Improvements in Bone Black Filters for g Gelatin Liquors and the Like, of

is a full, clear, and

Clarify which the followin exact description, re erence being had to the accompany' g drawings, forming a part of this specification.

My invention relates to the art of dutying and decolorizing gelatin liquors and the like such as glue liquors, glucose and sugar solutions, by means of bone black or animal charcoal, which is' commonly employed for such purpose because of its porous and absorbent nature, the method heretofore em-.

loyed being to filter the gelatin or other liquor to be treated, through a" bod of ground or granulated bone black hel between filter screens in a suitable container vessel; then removin the bone black when spent washing an re-burning it, replacing it in the container when so revivified and restored, and repeatin the first step of passing a fresh volume 0 gelatin or other liquor to be treated throug the container vessel and through the body of animal bone black so revivified and restored and replaced in the container as before stated.

My present invention hereinafter described and claimed has for its object the provision of an apparatus wherein, as a continuous rocess, I can preliminarily treat the granulated bone black in initial condition to deprive it of its combined salts and other imurities to' render it more efiicient in the first instance, then to pass a volume of gelatin or other liquor to be clarified through such purified body of bone black, then to revivify or clean the spent bone black without reburning and without removal from the container apparatus, and finally to re at the second ste of passing another voliime of gelatin or other liquor through the container vessel and its contained revivified essentially j pipe joint 6 with a vertical the container vessel, substantially closed to the atmosphere, preferably of the form of a frustum of an inverted cone, containing filtering devices near its opposite ends, and adapted to be filled with a body of granulated bone black between the same, valvecontrolled tubular means to discharge live steam upward through the container and its contents, tubular means to discharge a volume of hot water through the same in the reverse direction; tubular means to lead a volume of gelatin or other liquor to be treated to and from the o posite ends of the container, means within 1; e container, at its basal end, to deflect the entering steam, and preferabl with a plurality of interior valvecontrolle to every part of the container between' the filtering p ates.

In the accompanying drawings illustrating my sald invented apparatus, Figure 1 is an elevation, partly in section; Fig. 2 is a plan view; Fig. 3 is a section on the line 33 of Fi 1; Fig. 4 is an elevation of thesteamde ectin nozzle, detached, and Fig." 5 is a perspective view of a section of one-of the perforated steam-distributing tubular rings, detached.

Referring now to said drawings, the container vessel, indicated at 2, may be suitabl supported upon le S or standards 3. It 1s pre erably in the orm of an inverted frustum of a cone, having an inclination of about 1 to 3, the drawings showing a container which is 12 inches in diameter at base and 36 inches in diameter at top; and it is preferably a tinned co per vessel. As customary in the use of such devices when clarifying hot liquors, such as gelatin, the contalner should be wrapped with asbestos or other suitable means employed to prevent radiation of contained heat.- The container 2 has a base plate 2, integral or otherwise, and preferably curved, as shown; and said base is centrall apertured, to receive .the threaded end of a pipe 4 connected by an elbow joint 4" with a horizontally disposed pipe 5. Intermediate the length of the latter it is operatively connecte a sleevey-disposed same, the

steam pipe 6. Rearward ofv the pipe 5 is operatively embraced by horizontal another sleeve-joint connection 7 with steam pipe 7 governed by valve 7 The terminal the removable'closing cap 9 each with an annular flange 13, 13, whereby end of pipe 5 is governed by liquid spigot 8. The top end of the container 2 is. provided with a removable closing cap 9 centrally ap'u'tuied to receive a comparatively large inlet pipe 10, governed by a valve 10, and below this aperture I prefer to supply a deflecting plate, suchas the perforated plate" indicated at 10 to diffuse and spread the incoming hot water and gelatin liquor to be treated, so that it will discharge more evenly over the whole of the filtering device below it,'which consists preferably of a perforated plate 11 with superposed screen 11 both be- .ing detachably supported, within the contamer, by an annular bracket 12, the connection .bein by thumb-screw 12.

The top of the container 2 and the base of may be supplied they may be detachably connected as by thumb-screw 13 The container 2 is supplied near its top andabove its filter plates with large steam discharge openings, two being shown in the drawings at 14, 14, each of these receiving the threaded ends of pipe 15, which is governed by valve 15. Near the base of the container, another set of filtering devices 11, 11, the same as at top, is supported by like means 12, 12*, as before; and in the space between the same and the base plate 2 of the container 2 and over the large central aperture therein, is arranged, by its flange 16*, a cap. 16, shown in detached elevation in Fig. 4, and which serves a double purpose; first it is perforated as at l6 with perforations pointed directly vertical as to some of them and a vertical in cline outward as to the remainder, the function being to diffuse the incoming steam and spray it a ainst the whole surface of the lowering ltering device. Above the flange 16 of this cap 16, is arranged annularly a series of comparatively large holes 16", the function of which is to permit the passage of hot water and gelatin liquor treated, from the container into the pipe 5 to be discharged through the-nozzle 5 when,

in the operation sired.

Interiorly of the container 2 is arranged a plurality of annular-pipes or tubular rings 17 which are referably of tinned copper, like'the container vessel. The number of these willdepend upon the size and height of-the container vessel; and these tubular rings, shown in detached view in Fig. 5, are of a diameter to fit close against the inner wall of the container, and are perforated with a series of perforations 18 some pointing perpendicularly and others at one or more inclinations from the perpendicular,

of the device, it is so dethe function of each tubular ring and the series of them in conjunction with the basal perforated cap 16, being to diffuse and discharge the incoming steam, discharged through them, as indicated by the arrow in Fig. 1, against every particle of bone-black in the container vessel. Each of these tubular rings-17 is inde endently connected, by a pipe 19 passing through the wall of the container, said pi e being governed by its own valve19 and aving a sleeve joint conhence, the several steam inlets, shown as four in the drawin are'capable of either simultaneous or 0 independent action as. may-be desired. l

The operation of-the apparatus is as follows: Removing temporarily the detachable *closing cap 9 and upper filtering device 11, 11, the container is filled with ground or granulated animal charcoal or bone black, in the space between the upper and lower replaced, live steam is let into the container through pipe 5, discharged and diffused through perforated cap 16, the several annular perforate ipes 17 being then successively operated preferably beginning with the top tubular ring, and the steam thus reaching every particle of bone black is finally discharged through outlet pipes 15. The steam being blown upward prevents packing of the bone-black, which would otherwise occur, and is otherwise more eflective. After about twenty .minutes of such use, the steam inlet and exit pipes are closed and hot water admitted, from a suitable source of supply, through inlet pipe 10, the water thus passing, in a reverse direction and downward, through the'body of bone.

discharged through the ports 16' in the cap 16, passing out through pipe 5 by its terminal 5. The bone black being then in purified condition, gelatin liquor or other like material to be clarified and decolorized; is then admitted from a suitable source of supply through the same pipe 10, passing through the body of purified bone black in same ports and passages as the hot water, After one or more such applications, when, .from the appearance of the treated liquor, it shall be apparent to theoperator skilledin the art that the boneblack is spent, that ifs to say with its pores fillfl wit-h absorbed 0181 machine is then capable of cleaning and revivifying the spent bone black, and this without removal and re-burning, or either, by merely repeating the first described operation of cleansing its pores by a volume of live steam blown upward through it, followed by a hot water washing inthe reverse direction or downward. I

Having thus described my invention 1 claim asnew and desireto secure by Letters Patent 1. Apparatus for purifying bone-black nection 20 with the steam-supply pipe 6;
